Filed: 1981-03-16
Abstract: PURPOSE:To prevent the ground soiling of transfer paper and to increase the density of a toner image by making the peripheral speed of a donor member and the feed speed of transfer paper different from each other, and obtaining on the donor member charging distribution which extends in the driving direction of the donor member longer than the prescribed format of a toner image. CONSTITUTION:The peripheral speed V2 of a transfer roller 6 applying conveyance force to transfer paper 12 is made lower than the peripheral speed V1 of a donor roller 1 to increase the amount of toner supplied from the donor roller 1 to the transfer paper 12, and consequently the density of a toner image formed on the transfer paper 12 is increased and the dirtying of the texture part of the transfer paper 12 is suppressed. When the charging distribution of the toner is obtained on the donor roller 1 by applying a pattern signal to a mutlistylus electrode 5, a latent image is obtained being extended in the driving direction of the donor roller 1 longer than the prescribed format of an image expected to be formed on the transfer paper 12, and thus a toner image in prescribed format is obtained on the transfer paper 12.

Title: Integrated circuit
Inventor: KOIKE MITSUHIRO
IPC: H01L21/822
Filed: 1980-03-25
Abstract: PURPOSE:To contrive the improvement of a noise allowance degree for a supply power source of a digital circuit by a method wherein a capacity is formed in the IC between an electrode feeding a reference potential and an electrode feeding an another potential. CONSTITUTION:When the capacity 13 is connected in parallel between the reference electrode 12 grounded and the supply electrode 11 of the power source VDD and a parasitic resistor 14 is formed in series to the electrode 11 to form the integrated circuit, a noise amplitude is reduced even the noise enters into the supply power source VDD. The larger the capacity and the resistance value are, the more effective they are. The capacity 13 is easy to be formed in MOSIC and for this reason, the chip becomes not large. Generally, the capacity 13 is formed using a gate oxide film 17 between a substrate 15 and an Al wiring 16 with the substrate 15 as the reference potential. The resistor 14 is formed by a poly-Si layer. The power source VDD is supplied from a part (a) and fed from a part (b) to an internal logic circuit.  With this construction, the noise is completely removed and the noise allowance  degree of the digital circuit increases.

Abstract: PURPOSE:To prevent the breakdown of internal elements as well as a latch-up phenomenon when a power supply is applied, by connecing a transistor to a Zener diode in order to have a difference of time between positive and negative polarity power supply terminals of an operational amplifier. CONSTITUTION:Switching transistors (TR)Q11 and Q12 and Zener diodes ZD1 and ZD2 are connected to positive and negatice polarity power supply terminals  T1 and T2 of an operational amplifier 1. The diodes ZD1 and ZD2 have different  levels of Zener voltage in order to turn on the TRs Q11 and Q12 with a dif  ference of time when a power supply is applied. As a result, the TRQ11 is first  turned on and then the TRQ12 is turned on after a time equivalent to the dif ference of voltage between both power supplies when the power supply is ap  plied. As a result, the breakdown and a latch-up phenomenon can be prevented  for internal elements of the amplifier 1.

Inventor: SHINODA SHINICHI
IPC: H04N1/401
Filed: 1998-02-20
Abstract: PROBLEM TO BE SOLVED: To rapidly correct shading with high accuracy despite the variance of peak values of a reading signal by multiplying the input data by the peak value of data on a reference image and also multiplying the value of a signal peak register, i.e., the peak value covering up to the preceding line of the input data by the peak value of data on the reference image to perform the shading correction, based on those two multiplication results. SOLUTION: A 1st mode is a shading storage mode. In a signal reading mode, i.e., a 2nd mode, a shading waveform is read out synchronously with the reading of an image. Then an input signal VI is multiplied by a reference peal signal Vwp from a reference peak detection part 101 with a multiplier 106. Meanwhile, the shading waveform Vw stored in a shading storage part 102 is multiplied by the peak signal from a signal peak detection part 104 with a multiplier 107. The signal Vic multiplied by the multiplier 106 and the signal Vwc acquired through the multiplier 107 are inputted to a shading correction circuit 105 which performs the shading correction.

Title: Channel selection device for receiving digital television broadcast, receiver and method for channel selection
Inventor: TSURUMI ATSUSHI
IPC: H04N5/44
Filed: 1999-02-17
Abstract: PROBLEM TO BE SOLVED: To reduce a time required to start a service. SOLUTION: A tuner section 1 generates a local oscillation signal, multiplies it by a received 1st IF signal to convert the frequency of the local oscillation signal to convert it into a base band signal. A demodulation section 2 demodulates data from the base band signal received from the tuner section 1. The demodulation section 2 detects a signal level of the demodulated data and informs a control section 3 of the detected signal level. The control section 3 compares the signal level informed from the demodulation section 2 with a reference value stored in a storage section 4, and when the signal level is equal to the reference value or below, the tuner section 1 changes an oscillation frequency of the local oscillation signal used to convert the frequency of the 1st IF signal to select a channel in a succeeding frequency range.  Thus, a prescribed frequency range can be swept in a short time to select channels and the time required to start a service can be reduced.

Abstract: PURPOSE:To enhance a heat-exchanging efficiency, by immersing hydraulic apparatuses such as a hydraulic pump and an orifice in a working fluid contained in an oil tank, in a device whereby an oil discharged from a hydraulic pump driven by a wind mill or a water turbine is heated by ejecting it through an orifice. CONSTITUTION:When the hydraulic pump 2 is rotated by a wind force or hydraulic energy through a rotating shaft 1 of the wind mill or the water turbine, the working fluid 8 in the oil tank 7 is ejected through the orifice 6 after it is pumped by the pump 2 and its flow rate is regulated by flow control valves 4, 5. In this case, the mechanical energy loss of the pump 2, the pressure loss through throttling actions of the valves 4, 5 and the pressure loss in a pipe 3 are entirely transmitted to the working fluid 8 as heat, thereby preheating the fluid 8. The working fluid 8 thus preheated is further heated to a higher temperature by the generation of heat through a pressure loss when passing through  the orifice, and is then fed to a heat exchanger 10 provided in the exterior of  the tank 7. In the heat exchanger 10, water is heated by the high-temperature  working fluid, and is taken out as hot water.
